AMVA4NewPhysics' ESR at the INFN - Sezione di Padova. I work on the development of statistical learning techniques for Higgs boson analyses with data from the CMS experiment at the LHC.

The Night of European Researchers

by Pablo de Castro

This post is a summary of my experience last Friday at the European Researchers’ Night event in Padova. It was an interesting experience and gave me some insights regarding public outreach in these type of events which might be worth sharing and discussing here.

What could you do in a low-cost flight?

by Pablo de Castro

This post is the result of a self-imposed free-writing exercise while crossing on a plane, therefore it differs in format and content from my previous compositions. My aim was to write what I was thinking, without editing or overthinking. Here you go!

Tales of a nomadic researcher

by Pablo de Castro

This is a short essay about the perks and quirks of living away and travelling as part of the job description, which is part of the deal when you join a Maria Skłodowska-Curie Innovative Training Network (ITN) as AMVA4NewPhysics and might apply for the most part to other research positions. The points made here are based on my own personal experiences and discussions with people in analogous situations. I am eager to hear your thoughts regarding this matter in the comment section!

Are your analyses reproducible?

by Pablo de Castro

One of the main principles of the scientific method is reproducibility, which could be defined as the possibility to duplicate an entire experiment or study independently in the future.

For those doing scientific data analyses, like the members of this network, the same principle applies, so that all the data, methods, and tools should be provided and documented with enough detail to allow other researchers to obtain exactly the same results for the same datasets or to redo the analysis with new data. Do you think this is an unrealistic expectation or the way to go?

Hacker metamorphysics: SSH

by Pablo de Castro

It is about time for my second post of this technical series. This piece will include some tips and tricks that are useful when using Secure Shell (SSH) to access remote computers. It is a must-read if you have to write your username@hostname and password to access every time, you do not know what tunnelling is or you are annoyed by the inconvenience of having to access remote files.

You might have given a terminal multiplexer a chance (checkout my previous post on this series on that topic if not) but you are still not comfortable Continue reading “Hacker metamorphysics: SSH”

Smoothing alien data

by Pablo de Castro

What if you have some data you want to model, but do not know anything about its parent distribution, so you have to make as little assumptions as possible? In this post, I will go through the concept of density estimation and I will play with some interesting non-parametric methods.

Hacker metarmorphysics: tmux

by Pablo de Castro

This is the first post in a series which will go over some of the computing tools and practises that make my life as a scientific researcher easier. Today I will tell you about tmux and some of its use cases. Tmux is a modern terminal multiplexer and has become an extremely useful component of my remote data analysis and software development workflow.

Both in industry and in many scientific disciplines Continue reading “Hacker metarmorphysics: tmux”

MLHEP challenges

by Pablo de Castro

Hej! I am ashamed to say that this is the only Swedish I was able to learn at the 2nd Machine Learning in High Energy Physics Summer School you already heard about from Giles. ML-wise the school was quite instructive, though, especially due to competitions organized during the school. I also have a challenge for you!

Physicists ≠ Software Developers

by Pablo de Castro

Hey, it’s been a while since I wrote my last post! We’ve been quite preoccupied with hh → bbbb data analysis tasks and internal CMS presentations. I have several topics I want to talk about here so I will try to post more regularly in the following weeks. For today, I want to start a discussion about one important aspect of our job as scientists, which is software development. Continue reading “Physicists ≠ Software Developers”
